Object Height. Suppose an object is thrown straight up from the ground. The height after t seconds is given by the formula h(t) = -5t³ + 87t² + 204 (a) The time in seconds when the object reached the highest point was Note: Round to 4 digits after the decimal point, if rounding is required 26.1 s 8.7 s O None of the other answers O204 s OOS O 11.6 s (b) The height is maximized at the critical point x = a because the second derivative test found Of"(a) = 0 O f"(a) > 0 O f"(a) < 0 O f'(a) = 0 the right O f'(a) was positive to the left of x = a and negative O f'(a) was negative to the left of x = a and positive to the right
